All of the following statements are incorrect for noncyclic electron transport system, except

Electron transport between PS-II to PS-I produces ATP by substrate level phosphorylation.

In PS-II the oxidation of two water molecules produces four electrons, four protons, & a single

Water is oxidized & electrons are released by PS-1.

PS-II reduces NADP to NADPH.

Text Solution

Verified by Experts

The correct answer is:

Photophosphorylation (discovered by Amon) is of two types-cyclic and non-cyclic phosphorylation. Non cyclic photophosphorylation involves the participation of both PS I and PS II. The first step is photo-oxidation of water resulting in splitting of water into , e- and release of . It involves sequence of electron transfer where NADP is reduced by PSI. PS-I is reduced by PS-II and
PS-II is reduced by water so that the electro transport is non-cyclic.
